WINDOW REGULATOR..

Application filed March 25, 1927. Serial No. 178,203.

arms movable in unison to raise or lower the window. One or' the objectsof the invention is to so construct the window regulator that it may becheaply manufactured and assembled and easily operated to move thewindow through an extended range. Another object is to so construct thewindow regulator that the upper portion of the mounting plate may besecured to a lock board or other support or both its upper and lowerends may be secured to boards or supports. A further object is to soconstruct the window regulator that the pivotal means for the lifterarms may be located a substantial distance below the upper end of themounting plate and the handle 0r crank for actuating the 2o mechanismmay be located at the upper end of the mountingplate. With these as wellas other objects in view, the invention resides in the novel features ofconstruction and combinations and arrangements of parts as more fullyhereinafter set forth.

ln the drawings Figure 1 is an interior side elevation partly brokenaway of a motor vehicle door having applied lthereto a window regulatorembodying our invention; v

Figure 2 is an enlarged interior side elevation of the window regulator;

Figure 3 is an end View thereof;

Figures 4 and 5 are cross sections respectively on the lines 4-4 and5--5 of Figure 2;

Figure 6 is a view similar to Figure 1 showing a modified arrangement. y

lin the present instance we have shown the window regulator embodyingour invention as applied to a motor vehicle door having the verticallyslidable window 1 in the nature of a glass adapted to close the opening2 in the upper portion of the door or to be received in the chamber 3 inthe lower portion of the door, the window slidably engaging in the usualguide ways. 4 and 5 are vertically extending spaced inner and outermounting plates respectively` the outer mounting plate terminating shortof the inner mounting plate and being rigidly secured at its upper endin spaced relation to the inner mounting plate by the shouldered spacer6 having the lriveted ends 7. The lower end of the outer mounting plateAis rigidly secured in spaced relation to the inner mounting plate bysimilar shouldered spacers 8 while the intermediate portions of the twomounting plates are rigidly secured in spaced relation by the similarshouldered spacers 9. The upper portion of the inner mounting plate isin the nature or' an anchoring portion, it being provided with theopenings 10 for receiving screws or the like to secure the mountingplate to a lock board 11, as shown in Figure 1. The lower end of themounting plate also forms another Vanchoring portion l2, it havingopenings 13 for receiving screws or the like to secure the lower end ofthe mounting plate to a board 14, as shown in Figure 6, `at which timethe upper end of the mounting plate is secured to a board 15. Thislatter board may or may not be the lock board; The portion of the outermounting plate 5 opposite the lowermost openings 10 in the innermounting plate is provided with the aligned openings 16 to permit theinsertion of the screws or the like as well as 'suitable operating toolstherethrough While securing the inner mounting plate in place.

17 and 18 are the angularly movable lifter arms having their outer endssuitably operatively connected to the window and their inner endsrigidly secured to the gear segments 19 and 20, respectively. 21 and 22are the pivots for the lifter arms extending through the inner and outermounting plates 4 and 5, respectively, the gear segments 19 and 2O beingrigidly secured respectively to these pivots. 'The inner ends or' thepivots are provided wth transverse slots 23 for receiving the innermostends of the counterbalancing spiral springs 24, the outermost ends ofwhich are provided with hook-s to engage the lugs 25 upon the innermounting plate 4. The gear segments are located between the inner andouter mounting plates and in order to locate the pivots for the lifterarms adjacent to each other and at the same time provide for thenecessary leverage to swing the lifter arms the gear segments arelaterally offset and overlap each other.

To rotate the gear segments in unison, we have provided the verticallyreciprocable rack member 26 located between the inner and outer mountingplates and having at its lower end the laterally odset internal racks 27and 28 facing each other and meshing respectively with the gear segments19 and 20. This rack member is provided at its upper end and along oneof its edges with the external rack 29 extending parallel of the otherracks and meshing with the pinion 30, whlch is rotated in unison withthe gear 3l, the pinion and gear being mounted upon the shaft 32extending between the inner and outer mounting plates. 33 is a secondpinion meshing with the gear 3l and adapted to be driven from thedriving shaft 34 through suitable clutch mechanism within the cup 35,the driving shaft having secured to its inner end the handle or crank36. The cup 35 is rigidly secured to the inner mounting plate and as aconsequence the driving shaft may be said to be mounted upon the innermounting plate. Furthermore, the pinion 33 is mounted upon the pin 37having one end mounted in the outer mounting plate and the other endmounted in the driving shaft and consequently upon the inner mountingplate.

The rack member 26 has the lower portions of its edges 26 below theexternal rack 29 slidably engageable with the shoulders spacers 8 andthe pivots 2l and 22. For holding the external rack 29 in mesh with thepinion 30 there are the lugs 38 and 39 which are preferably struck outfrom the mounting plates and extend transversely thereof to engage theinner and outer edges of the rack member 26 facing in a directionopposite to that of the rack 29.

With the above construction it will be seen that the rack member iseectively guided during its reciprocation and that it simultaneous yactuates the gear segments and thereby swings the lifter arms in unison.It will also be seen that the handle or crank for actuating themechanism is located at the upper end of the mounting plate, while thepivots for the lifter arms may be located near its lower end. It will befurther seen that the construction is such that it provides for a verysimple form of reduction gearing. In addition to these features and ofdecided importance is the fact that separate pivots are provided for thelifter -arms and arranged adjacent to each other.

What we claim as our invention is:

l. In a window regulator, the combination with a pair of angularlymovable lifter arms,
